A Stratford doctor has filed a prospective class action federal lawsuit against a digital media company for sending unauthorized and unwanted fax advertisements promoting its health-related television programming to doctors’ offices.

In his 11-page lawsuit, filed Monday in U.S. District Court in New Haven, Dr. Kenneth A. Thomas said that Darien-based Hospital Media Network (HMN) has caused him and others “actual harm, including the aggravation and nuisance of receiving such faxes, the loss of use of their fax machines during the receipt of such faxes, increased labor expenses, and the loss of any ink and paper used to print them.” Thomas claims that none of the faxes contains the requisite “opt-out notices” mandated by federal law. Hospital Media Network is also known as Health Media Network
